So... I was in my car at lunch today with the ac running and all of a sudden the blower fan stops. After messing with it I can see that it works fine on speeds 3 & 4 but 1 & 2 don't work anymore. I checked all the fuses and relays and tried banging around the dash and ac system under the dash but I can't get 1 & 2 to work. Any body have this happen or know what it could be???
